Conspicuity Tape / Visibility Markings

Hi;

We spend a lot of time discussing electronic collision avoidance
devices, and advice to keep a good lookout. To help the situation we
could also make our aircraft more visible to those what are keeping
that good lookout. Isn't some sort of visibility marking required in
Europe?

A search of the group reveals that this was discussed extensively in
the 90's, and mentioned occasionally since, but is anyone aware of new
technology that is useful? These days you can get holographic,
prismatic, and various coloured reflective tapes, almost all of it for
trucks, industrial equipment, or decoration, but most of it doesn't
seem too useful in daylight.

I have searched high and low and found a lot of mediocre products for
our purpose.. The people at the link below have selections from 3M
and just about anyone else in the business. (no connection etc)

Has anyone found anything really good?
